PLATE-CLAMP-OPERATING TOOL.

`r :specification of reis/tersraient.` Patnted May 2', 1922,

Originalfapplication filed November 10, 19715, Seria1- No.60,652. l Divided and'tliis application ile'd Februaryy 11,1918. Serial No. 216,473. f

To afZMo/Lom t 'may concer-1t ,Be it known that we, ,OSCAR` RoEsnN and .IsrDon TORNBERG, citizens of the .United States, residing atNew York city, kcounty ofIings,'State oi' New York, have invented `certain `new and, usefulv Improvements in vPlate Clamp Operating Tools, fully described and representedV inthe following specification, and "the accompanying drawings, forming a partof the same.

This invention relates to certainimprove- .ments in tools for operating plate clamps, yand the tooll has been particularly designed jlfor operating the clamp shown and described iny ourvjoint application Serial No. 60652, filedk November l0, 1915, of whichapplica- 'tion the present application is a division, the

subject-matter whereof was divided out of the Original application by Patent Oflice` requirement;v f y -The especial object of the present invention is to provide'an improved tool which canj be readily .positioned inl'relation to the Y clamp, and firmly and, securely locked in .such positionV so that theclamp may bead- 1 justed readily and accurately withfrelation Vto the plates.`y While the tool ofthe present application may be usedin other relations and with other types Offclamps,v` it has been designed particularly for use' with the clamp v v vthereis provided bythe present invention an shown and described in our application above referred to, to which reference maybe had for a full understanding of the construction, .To enable the useof this tool with'such clamp to be fully understood, such clamp will be briefly described in this application in connection with the accompanying drawings, which. show the clamp and' the tool 'inf operativel relation therewith. In

these'drawings-' Figure 1 is a side proved tool;Y i i A Figure 2 is an end elevation, partly in section,fwithv certain parts broken away, showing the'tool in` operative relation with the clamp:

Figure 3 is a cross sectional view, partly elevation of fthe Vimf broken away, of the clamp and the Operative part of the tool show-n in operative relation with the clampI` .and

Figure 4 is a detail sectional view taken on theline 4w4 of Fig; 2.

Referring now to these drawings, the

clamp includes an adjustable member 1,V

clamp g to' move with the nut.

Cooperating with this two-part head 4, 5 connected by a web 6. This carrier is anchored'to the base by positioning the head 4 of the screw and the vweb 6 in a slot 7 formed in one end of the Abase 1, the screw being prevented from turningby iiattening one of the heads as shown at 8. The plate clamp, marked I9, is movable onuthe carrier so as to position the clamp in proper' relation to the plate for adjusting the plate relatively to the bed, which movement is effected by thetool hereinafter described. Vhile this may be effected in various ways, a clamp moving device is provided consistingof a nut 10 on the threaded shank 3, before referred to. This nut is provided 'witha flange 11 vwhich takes into a groove 12in the clamp, thus causing lthe gear nut having a gear or wheel 13. When vthe gearfsturned Ythe clampmove'r is vadvanced or, draggedalong the shank ofthe carrier' and the plate consequently locked or unlocked from clamping position'or moved yfor adjustment.

For operatingk this and similar clamps,

improved tool, the specificconstruction of which may-vary.y In the best embodimentsV of the tool, however, it will be provided with `vmeans for cooperating with the clamp, whereby the tool is held in rigid locked relation'with the clamp during the clamp-ad- 'y In the best justing or moving operation. embodiments of the tool, furthermore, the operative parts of the tool will be'enclosed in a head or casing, so that the operator A will belprotected from k.the moving parts and theirnoving'parts of thetool will'jbe protected from dust or dirt, or other foreign substances which, getting into the operative parts. might iniure them.

Thisnutisa Y finto aufgroove 19 in the shaft.

17 passes through ahead 2O of-the casing the clamp. ln the best constructions, to permit the moving` parts to be assembled in as small vspace as possible,thus permitting ay small,handy tool, miter gearsvmaybe employed and the Vhandle will be vertically arranged with respect to thetool. vVVhil'e the specic arrangement of these gears may be somewhat varied, `*in the particular construction shovvn there is a vertical operating shaft 17 suitably.v 4'fixed to j the operating handle 15, as by a set screw v1:8 passi-ng through the Wall oit the handle and taking The shaft and takes bearing in the lower wall 21 of the head, this wall being preferably a sloping one, as shown in Fig. 3, to enable the tool to be easilyl .and accurately adjusted with respect to the clamp. This operating shaft 17 carries aimiter 22 which ymeshes with a miter 2301i a stud 24, taking bearing in the Walls 21 and of thehead. Fast on the study 211 is a gear Q'located in the head7 Vwhich gear operates a pinion 27 mounted onv a stud 28 lwhich takes bearing iin a projection Q9 depending from the head let, thetee'th-ofthe Apinion projecting from the head through asuitable opening in the projection. n

W 1th this constriution the operative parts are protected, so1thlat dirt and other foreign substances are not easily accessible to thein,`

and the operator is protected from any moving parts. rl".uithermore, by the arrangement adopted, the gearingyoccupiesa-small space.

The means whereby .the tool may be positively' held in voperative relation with the These; jaws are, furtl'iermore,"4 preferably spring jaws7 beingheld in Alocking relation with the clamp bymeans of springs 34,' lagainst which the'javvsfare rocked to release them from the clamp. wWith this construction thetool-is positively heldin locked/relation with the. clamp, but may be easily mz-iiiipulated to Vveifect the clamp adjusting operation. f

Tools embodying the invention in its best form will also be provided with means forassisting in positioning them in proper relation to theoperating gears yor Walls of the clamps. llhile these means may be varied2 in the particular construction illustrated the Wall 21 of the head isl providedivith one or more positioning pin-s 35, which are arranged to enter a suitable hole` or slot 36 formed in the edge of the (il'ainp,l i

thesepins acting to position the tool in proper relation with the clamp gear .or Wheel.y

"While the invention has been shownfand vdescribed in its preferred form, it Will vbe understood that various 'changes may be made in the' specic construction shown and described, Without departing from the inone'vof saidggears co-operating with the* adjusting' mechanism a plate clamp, and a positioning device projecting from' the beveledA side of the casing for positioning the casing Withre'spect lto a clamp.

combination with a tool body, of a pairof locking/jaws pivoted thereto, and springs for holdingrth'e locking jaws inpositive lockedl relation with a plate clamp.

3. In :a .plate clamp operating'tool, the`A combination with Vanwenclosed casing, of

.plate Y clamp adjusting devices mounted therein, and a pair of pivoted locking jaws mounted loutside `the casing forpositively locking the casing in operative relation With the plate clamp.
